FASTENING DEVICE FOR WlNDOW-SASHES.

SPECIFICATION forming part of Letters Patent No. 635,982, dated October 31 1899.

Application filed January 23,1899, Serial No. 703,053. (No model.)

To all whom it may concern.-

Be it known that I, AMOS H. SMITH, a citizen of the United States, residing at New York,

upper sash and the top of the lower sash together, so as to prevent rattling and shaking of the sashes.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which- Figure 1 is a plan view of the bottom part of the upper sash and the upper part of the lower sash and showing my improved sashlock or fastening device connected therewith Fig. 2, a section on the line 2 2 of Fig. 1; Fig. 3, a front view of the device as shown in Fig. 1; Fig. 4, a section on the line 4 4 of Fig. '1, and Fig. 5 a section on the line 5 5 of Fig. 1.

In the drawings forming part of this specification the separate parts of my improvement are designated by the same numerals of reference in each of the views, and in said drawings I have shown at 7 the upper part of the lower sash and at 8 the bottom of the upper sash, and in the practice of my invention I provide a fastening device for the purpose herein described, comprising two separate parts 9 and 10, the first of which is de signed to be connected with the bottom part of the upper sash and the second with the top of the lower sash.

The part 9, which is connected with the bottom of the upper sash, consists of a plate provided with a central raised casing 11, which is open at the front and provided at one side with a pin 12. I

The part 10, which is designed to be secured to the top of the lower sash, consists of a plate provided with a central transverse raised casing 13, the rear end of which is bolt 17, which is adapted to be projected baclo wardly or outwardly into the casing 11 by a' spring 18, and the front end of the bolt 17 is cut away on the under side to form a recess 19, in which said spring is placed, and pivotally connected with said bolt at 20 is a leverbar 21, which projects through the slot or opening 15 in the front end of the casing 13 and is provided with a ring or handle 22, and said lever-bar 21 is provided rearwardly of its front end with a downwardly-directed shoulder or projection 23, and by pulling said lever-bar outwardly until the rear end of the shoulder or projection 23 engages with the bottom of the slot or opening 16 the bolt 17 will be withdrawn within the casing 13, as shown in said figure, and by raising said leverbar until the shoulder or projection 23 is dis connected from the bottom of said slot or opening the bolt 17 will be projected into the casing 11, as shown in Fig. 4, and the sashes will be locked together.

The bolt 17 is cut away longitudinally at its top, as shown at 24, and passing through the top of the casing 13 is a pin 25, on which is pivoted a backwardly-directed curved arm 26, which operates in the slot or opening 14, and is provided at its rear end with a crosshead 27 and with a downwardlydirected curved finger 28, and the bolt 17 is provided, on the left-hand side thereof, with a pin 29, with which said finger is adapted to engage when the bolt 17 is drawn forwardly and disconnected from the casing 11, as shown in Fig. 5.

Pivoted to the right-hand side of the casing 13 and at the bottom thereof, as shown at 30 in Fig. 2, is a dog 31, provided with a downwardly and backwardly directed finger 32 and in the body portion thereof with an inclined slot 33, and passing through the slot 33 is a pin 34, which passes through the slot or opening 16 in the side of the casing 13 and into the bolt 17, with which it is connected, and the finger 32 of the dog 31 is adapted to engage with the pin 12, secured to the casin g 11 when the sashes are locked together, as shown in Fig. 2.

The arm 26 is extended below its pivot 25 in the form of a segmental or cam-shaped projection 35, which upon the movement of the arm 26 as the weight 27 drops engages the inner or rear end of the lever 21.

The normal position of the parts when the sashes are locked together is shown in Fig. 4, and in order to operate the device so that the sashes may be adjusted or the upper sash lowered or the lower sash raised the bolt 17 is drawn outwardly by the lever-bar 21, as shown in Fig. 5, and held in such position by said lever, the shoulder or projection 23 engaging with the bottom of the slot or opening 16, and as the windows, or either of them, are opened the weight 27 and the arm 26 drop downwardly, whereupon the finger 28 of said arm engages with the pin 29 and also holds the bolt in the withdrawn position, or that shown in Fig. 5. As the weight commences to drop, the projection 35 011 the lower end of the arm 26 strikes the inner or rear end of the lever 21, depressing the same and correspondingly raising the forward end of said lever, thereby releasing it from engagement with the lower edge of the slot 16, whereupon the said lever 21 has no further locking action or hold upon the retracted bolt 17, which is, however, held in such retracted position by engagement of the curved finger 28 with the pin 29 of said bolt, it being noted that this finger engages said pin before the projection 35 releases the lever 21, and so long as the weight remains down the finger 28 will hold the bolt against projection. If now it is desired to lock the sashes together, the lower sash is moved downwardly or the upper sash upwardly. In this operation the head or weight 27 of the arm 26 strikes the top of the casing 11 and is forced upwardly, releasing the pin 29 from the finger 28, and the front end of the lever-bar 21 being already raised or released the spring 19 throws the bolt 17 backwardly into the casing 11 and the sashes are locked together, and at the same time the pin 34:, which is secured to the bolt 17, operates the dog 31 and causes the finger 32 thereof to engage with the pin 12, secured to the side of the casing 11, and draws the sashes together, as will be readily understood.

My improved sash-lock or fastening device is simple in construction and operation and perfectly adapted to accomplish the result for which it is intended and it will be apparent that changes in and modifications of the construction described may be made without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A sash-lock comprising two casings, one of which is adapted to be secured to the lower, and the other to the upper sash, the adjacent ends of which are open, a normally-projected bolt mounted in the casing which is adapted to be secured to the lower sash, means for retracting said bolt and for holding it temporarily in a retracted position, means for automatically releasing the temporary retracting means and at the same time engaging the bolt to hold it while retracted, the same embodying a movable projecting part, which, when the windows are closed, will be actuated to entirely release the bolt and permit the same to project operatively, substantially as shown and described.
